SUCKER-ROD SOCKET.

SPECIFICATION forming part of Letters Patent No. 578,344, dated March 9,1897.

Application filed May 2, 1896. Serial No. 589,983. (No model.)

To all whom, it may concern.-

Be it known that we, BENJAMIN MASSETH and DAVID NV. BLACK, of Butler, inthe county of Butler and State of Pennsylvania, have invented a new anduseful Improvement in Sucker-Rod Sockets, of which the following is afull, clear, and exact'description, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a side elevation of our improved socket. Fig. 2 is a partiallongitudinal section of the same on a larger scale. Fig. 3 is a sideelevation, partly broken away, to show the spring-jaw; and Fig. 4 is across-section on the line IV IV of Fig. 2.

Our invention relates to the sucker-rod sockets which are used in deepwells of small diameter, such as those in which a two-inch casing isemployed. In sockets for such use it has been found extremely diflicult,if not impossible, to get sufficient thickness of metal in the hollowtube forming the body of the socket to allow the requisite securing ofthe jaw or jaws in place, while at the same time allowing sufficientinternal diameter inside the jaws to allow entry df the suckerrodtherein. This difficulty has been entirely overcome by our invention,which consists in providing a tube having an eccentrically-placed holetherein, thus giving on one side of the tube sufficient thickness forplacing and suitably securing the jaw in position.

We will now describe our invention as ap-v plied to a socket of thegeneral type shown and described in our former patent, No. 535,709,

. granted March 12, 1895, though we do not wish to be understood as inany wise limiting our invention to such type.

As shown in Figs. 2 and l, we form a tube 2 with an eccentric holetherethrough, one side 3 of the tube thus being thickened sufficientlyfor the attachment of the spring-j aw 4. This jaw 4 is formed with ashank-piece 5, having V-shaped edges arranged to fit within grooves atthe side of a longitudinal slot in the thicker side of the tube, and atits lower end is provided with a head or gripper 6, having innerupwardly-inclined teeth to bite upon the sucker-rod. The slot in thetube is enlarged at its upper end, as shown, to allow entrance of theshank to the guiding-grooves, after which a stop-block 7 is secured inthe enlarged portion, thus preventing the upward sliding of the jawbeyond the normal position shown. The slot is also enlarged at its lowerend sufficiently so that when the stop-block is removed and the jawmoved upwardly the head will spring out through this enlargement andrelease the sucker-rod. The tube is provided at its upper end with theusual screwplug and at its lower end is rounded or beveled outwardly toallow easy entrance of the rod.

The advantages of our invention will be apparent to those skilled in theart, since a tool is provided which can be advantageously used in smallholes, the jaw being easily and securely fastened in the tool and alsodetached from the rod without diffioulty.

Modifications in the form, construction, and arrangement of the parts ofthe device may be made by the skilled mechanic without departure fromour invention, since What we claim is 1. A sucker-rod socket consistingof a tube having an eccentric hole therein, and a jaw secured in thethicker portion of the tubewall, substantially as described.

2. A sucker-rod socket consisting of a tube having an eccentric holetherein, and a sliding jaw secured in the thicker portion of thetube-wall, substantially as described. 3. A sucker-rod socket consistingof a tube having an eccentric hole therein, a slot in the thicker sideof the tube, and a sliding springjaw movable within said slot,substantially as described.

In testimony whereof we have hereunto set Witnesses:

ALEX. MITCHELL, ANDREW G. WILLIAMS.
